- Food environments in schools and in the immediate vicinity are associated with unhealthy food consumption among Brazilian adolescents(2016) AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; CANELLA, Daniela Silva; CLARO, Rafael Moreira; PERES, Maria Fernanda Tourinho; LUIZ, Olinda do Carmo; FRANCA-JUNIOR, Ivan; KINRA, Sanjay; HAWKESWORTH, Sophie; LEVY, Renata BertazziBackground. Evidence of the influence of the school food environment on adolescent diet is still little explored in low-and middle-income countries. We aimed to evaluate the association between food environment in schools and the immediate vicinity and the regular consumption of unhealthy food among adolescents. Methods. We used cross-sectional data collected by the Brazilian National Survey of School Health (PeNSE) from a representative sample of adolescents attending 9th grade public and private schools in Brazil, in 2012. We estimated students' regular consumption (>5 days/week) of unhealthy food (soft drinks, bagged salty snacks, deep fried salty snacks and sweets) and school availability, in the cafeteria or an alternative outlet, of the same food plus some healthy options (fruit and natural fruit juice). We performed multilevel logistic regression models. Results. Having a cafeteria inside school selling soft drinks (private schools OR = 1.23; 95% CI = 1.14-1.33; public schools OR = 1.13; 95% CI = 1.06-1.20) and deep fried salty snacks (private schools OR = 1.41 95% CI = 1.26-1.57; public schools OR = 1.16 95% CI = 1.08-1.24) was associated with a higher consumption of these unhealthy foods of among students. In private schools, cafeteria selling fruit and natural fruit juice was associated with lower student consumption of bagged salty snacks (OR = 0.86; 95% CI 0.77-0.96) and soft drinks (OR = 0.85; 95% CI = 0.76-0.94). In addition, eating meals from the Brazilian School Food Program in public schools was associated with a lower consumption of unhealthy foods. Conclusions. Foods available in the school food environment are associated with the consumption of unhealthy food among adolescents in Brazil.
- Sociodemographic and behavioral factors associated with physical activity in Brazilian adolescents(2014) REZENDE, Leandro Fornias Machado de; AZEREDO, Catarina Machado; CANELLA, Daniela Silva; CLARO, Rafael Moreira; CASTRO, Ines Rugani Ribeiro de; LEVY, Renata Bertazzi; LUIZ, Olinda do CarmoBackground: Physical activity in adolescents is associated with short-and long-term health benefits. Physical activity can occur in various domains and is influenced by a complex network of factors. The aims of this study are 1) to describe the physical activity of Brazilian adolescents in physical education classes, during leisure time, and during active commuting and 2) to investigate the socio-demographic and behavioral factors associated with physical activity. Methods: The representative sample included 109,104 Brazilian students in the final year of elementary school from 2,842 schools. The weekly frequency and duration of physical activity were assessed. A variety of socio-demographic and behavioral factors were studied. A multiple Poisson regression analysis was used to test for associations between physical activity and the socio-demographic and behavioral variables. Results: Most of the students (97.0%) engaged in physical activity in at least one of the domains studied, especially physical education at school (81.7%) and leisure time physical activity (67.5%). However, only 29% of the adolescents reached the recommended level of physical activity. Among the adolescents who reached the minimum recommended time for physical activity, the various domains contributed the following proportions to total physical activity: leisure time physical activity (PR 12.5; 95% CI 11.17-13.97), active commuting (PR 1.63; 95% CI 1.59-1.67), and physical education at school (PR 1.36; 95% CI 1.29-1.44). The weekly frequency of all activities was greater among boys than among girls. Moreover, nearly two-thirds (61.8%) of students spent more than two hours per day engaging in sedentary behaviors; the prevalence of sedentary behaviors was similar between boys and girls (59.0 and 64.5%, respectively). Total level of physical activity, leisure time physical activity, and active commuting were associated with higher nutritional scores. Conclusions: Physical activity is important in any health promotion program. Therefore, it is necessary to invest in policies and interagency initiatives that promote all domains and to ensure that the general population helps determine the scope and design of such policies.
- Coronary heart disease mortality, cardiovascular disease mortality and all-cause mortality attributable to dietary intake over 20 years in Brazil(2016) REZENDE, Leandro Fornias Machado de; AZEREDO, Catarina Machado; CANELLA, Daniela Silva; LUIZ, Olinda do Carmo; LEVY, Renata Bertazzi; ELUF-NETO, JoseBackground/objectives: In the last two decades, in Brazil, there has been a decreasing trend of consumption of in natura or minimally processed food, while intake of ultra-processed food has markedly increased. We estimated the contribution of dietary intake in trends from coronary heart disease mortality (CHDM), cardiovascular disease mortality (CVDM), and all-cause mortality (ACM) over 20 years in Brazil. Methods: We used a representative sample of Brazilian households located in metropolitan areas to estimate dietary intake in 1987/88 and 2008/09. For both periods, we estimated fractions of CHDM, CVDM, and ACM attributable to healthy (fruits and vegetables) and unhealthy food items (sugar-sweetened beverages, processed and red meat). We also estimated the number of prevented or postponed deaths attributable to these food items. Results: The fraction of CHDM attributable to all food items increased from 28.6% in 1987/88 to 38.7% in 2008/09. CVDM attributable to food items increased from 13.7% in 1974 to 19.3% in 2008/09. ACM attributable to all food items increased from 20.1% in 1987/88 to 27.3% in 2008/09. Without the decrease in healthy food item consumption, and the increase in unhealthy food items, 3195 deaths from coronary heart disease, 5340 from cardiovascular disease, and 16,970 from all causes could have been prevented or postponed. Conclusions: The burden of cardiovascular diseases and mortality attributable to dietary intake has increased over the last 20 years in Brazil. These findings suggest a need for a population prevention approach, focused on dietary intake to reduce the burden of disease.
- The influence of lifestyle and gender on sickness absence in Brazilian workers(2014) RABACOW, Fabiana Maluf; LEVY, Renata Bertazzi; MENEZES, Paulo Rossi; LUIZ, Olinda do Carmo; MALIK, Ana Maria; BURDORF, AlexBackground: Despite an increasing body of knowledge concerning gender and lifestyle factors as determinants of sickness absence in well-developed countries, the relationship between these variables has not been elucidated in emerging economic power countries, where the burden of non-communicable diseases is particularly high. This study aimed to analyze the relationships among lifestyle-related factors and sick leave and to examine whether gender differences in sickness absence can be explained by differences in socio-demographic, work and lifestyle-related factors among Brazilian workers. Methods: In this longitudinal study with a one year follow-up among 2.150 employees of a Brazilian airline company, sick leave was the primary outcome of interest. Independent variables collected by interview at enrolment in the study were gender, age, educational level, type of work, stress, and lifestyle-related factors (body mass index, physical activity and smoking). In addition, the risk for coronary heart disease was determined based on measurement of blood pressure, total cholesterol and glucose levels. The total number of days on sick leave during 12 months follow-up was available from the company register. Logistic regression analysis was used to determine the influence of socio-demographic, type of work and lifestyle-related factors on sick leave. Results: Younger employees, those with lower educational level, those who worked as air crew members and those with higher levels of stress were more likely to have sick leave. Body mass index and level of physical activity were not associated with sick leave. After adjustment by socio-demographic variables, increased odds for 10 or more days of sick leave were found in smokers (OR = 1.51, Cl = 1.05-2.17), and ex-smokers (OR = 1.45, Cl = 1.01-2.10). Women were more likely to have 10 or more days of sick leave. Gender differences were reduced mainly when adjusted for type of work (15%) and educational level (7%). Conclusions: The higher occurrence of sick leave among women than among men was partly explained by type of work and educational level. Our results suggest that type of work, a stressful life, and smoking are important targets for health promotion in this study population.

- Dietary intake of Brazilian adolescents(2015) AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; CANELLA, Daniela Silva; CLARO, Rafael Moreira; CASTRO, Ines Rugani Ribeiro de; LUIZ, Olinda do Carmo; LEVY, Renata BertazziObjective: To analyse the dietary intake of Brazilian adolescents and investigate its association with sociodemographic factors as well as health-risk and health-protective behaviours. Design: Cross-sectional study. Setting: The study was based on data supplied by the National Survey of Schoolchildren's Health (2012) on sociodemographic factors, dietary intake and health-risk and health-protective behaviours of schoolchildren in Brazil. A nutritional scale was elaborated combining markers of healthy and unhealthy diets. Poisson regression analysis was applied to investigate the association between the sociodemographic factors and regular intake (>= 5 times/week) of selected foods; linear regression analysis was applied to investigate the association of sociodemographic and behavioural factors with nutritional scale score. Subjects: A total of 109 104 adolescents attending the ninth year of education at 2842 schools in Brazil. Results: Fewer than 30 % of the adolescents consumed raw or cooked vegetables on a regular basis, whereas more than one-third reported regular intake of sweets, soft drinks and sweet biscuits. Adolescents from the southern area and the oldest ones were those most exposed to inadequate dietary intake. The nutritional scale average score was higher in the students attending public school and exhibited a positive correlation with protective behaviours, such as being physically active, having meals with parents and eating breakfast, and a negative correlation with risk behaviours such as eating while studying or watching television and having smoked, drunk alcohol or used other drugs in the previous 30 d. Conclusions: The results indicate an association between undesirable nutritional habits and other risk behaviours among Brazilian adolescents.
- BEING YOUNG-BLACK-MALE INCREASES THE ODDS OF SUFFERING POLICE NON-LETHAL VIOLENCE IN BRAZIL, ACCORDING TO THE NATIONAL HEALTH SURVEY 2013(2018) PERES, Maria Fernanda; LEVY, Renata Bertazzi; REZENDE, Leandro Fornias Machado de; LUIZ, Olinda do Carmo; GRANGEIRO, Alexandre
- The Role of School Environment in Physical Activity among Brazilian Adolescents(2015) REZENDE, Leandro Fornias Machado de; AZEREDO, Catarina Machado; SILVA, Kelly Samara; CLARO, Rafael Moreira; FRANCA-JUNIOR, Ivan; PERES, Maria Fernanda Tourinho; LUIZ, Olinda do Carmo; LEVY, Renata Bertazzi; ELUF-NETO, JoseObjective To analyze the association of physical activity facilities and extracurricular sports activities in schools with physical activity among adolescents. Methodology/Principal Findings We used data collected for the National Survey of School Health in 2012. The national representative sample comprised 109,104 Brazilian students from 2,842 schools. We calculated the prevalence of participation in physical education classes, leisure-time physical activity, and total physical activity level. We also evaluated the following physical activity facilities: sports courts, running/athletics tracks, schoolyard with teacher-directed physical activities, swimming pools, locker rooms; and the offer of extracurricular sports activities. Schools with at least one physical activity facility had increased odds of participation in physical education (OR 1.59; 95% CI 1.20 to 2.10). However, in order to increase leisure-time physical activity (OR 1.14; 95% CI 1.03 to 1.26) and total physical activity level (OR 1.15; 95% CI 1.06 to 1.24) at least four and two facilities, respectively, were necessary. Extracurricular sports activities in schools were positively associated with leisure-time physical activity and physical activity level. The number of sports courts and swimming pool in a school were associated with participation in physical education classes. Availability of sports courts, running/athletics tracks, and swimming pool in schools were associated with leisure-time physical activity. Total physical activity was associated with schools with sports courts, schoolyard with teacher-directed physical activities, and swimming pool. Conclusions School-level characteristics have important potential to increase the possibility of engagement in physical activity in and out of school, and therefore have a fundamental role in promoting these practices.
article 18 Citação(ões) na Scopus Recomendações para atividade física e saúde: consensos, controvérsias e ambiguidades(2014) LIMA, Dartel Ferrari de; LEVY, Renata Bertazzi; LUIZ, Olinda do CarmoObjective. To compare the results of physical activity (PA) classification according to five international guidelines (American College of Sports Medicine, Institute of Medicine, Advisory Committee on International Physical Activity Questionnaire, World Health Organization, and European Union). Methods. Cross-sectional study with 52 779 adults of both sexes, living in state capitals and the Federal District, selected using probability sampling. Data about duration, intensity, and frequency of weekly PA were obtained from a yearly survey conducted by the Health Ministry of Brazil (Risk and Protection Factors for Chronic Diseases Telephone Surveillance System-VIGITEL). Results. The percent of participants classified as inactive by the five recommendations was similar. Among those who reported having engaged in PA, 45% were classified in the same activity level by all five guidelines (24.8% as insufficiently active, 10.6% as active, and 9.1% as very active). For the additional 55% who reported having engaged in PA, different classifications were obtained, ranging from insufficiently active to very active depending on the guideline. Conclusions. Nuances in the criteria used for each guideline translated into differences in classification of PA. Even though the overall goals of all guidelines are the same, the lack of agreement regarding the minimum recommended amount of PA impacts the development of policies to promote PA.- Personal, relational and school factors associated with involvement in fights with weapons among school-age youth in Brazil: a multilevel ecological approach(2018) PERES, Maria Fernanda Tourinho; AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; ZUCCHI, Eliana Miura; FRANCA-JUNIOR, Ivan; LUIZ, Olinda do Carmo; LEVY, Renata BertazziObjectivesTo investigate the association between personal, relational and school factors with involvement in fights with weapon among Brazilian school-age youth.MethodsUsing data from the Adolescent School-Based Health Survey 2015 (n=102.072), we conducted multilevel logistic regression models.ResultsIFW was associated with female sex (OR=0.45), and with older age (OR=1.15), previous involvement in physical violence (OR=2.05), history of peer verbal (OR=1.14) and domestic victimization (OR=2.11), alcohol use (OR=2.42) and drug use (OR=3.23). The relational variables (e.g., parent's supervision) were mostly negatively associated with IFW. At the school level, attending public school and attending schools in violent surroundings were both positively associated with IFW. The intraclass correlation coefficient estimated in the empty model showed that 5.77% of the variance of IFW was at school level. When all individual- and school-level variables were included in the model, the proportional changes in variance were 61.7 and 71.55%, respectively.ConclusionsIFW is associated with personal, relational and school factors. Part of the variance in IFW by school is explained by characteristics of the school context.
